What I'm looking for

I seek roles building scalable cloud systems and data pipelines with strong CI/CD practices, collaborative teams, and impact on product reliability and cost transparency.

I am a senior software engineer with experience building cloud-native billing and cost-management features, high-throughput data pipelines, and responsive web services. At Microsoft I led development of features that reduced billing-discrepancy tickets by 41%, cut processing latency by 52%, and improved tag-based cost allocation accuracy by 90%.

I design end-to-end solutions spanning REST APIs, React front ends, Spark and Synapse pipelines, and CI/CD automation, and I prioritize secure, high-quality deployments and synthetic testing to catch regressions early. I also modernized high-traffic web tolling and payment systems, improving performance and analytics to shorten reporting cycles from weeks to hours.
